[root@Nagios ~]# yum install -y httpdphp[root@Nagios~]# yum install -y gcc glibc glibc-common

[root@Nagios~]# yum install -y gd gd-devel

[root@Nagios~]# yum install -y perl ntp unzip[root@Nagios~]# yum install -y openssl-devel

[root@Nagios~]# /etc/init.d/ntpd start

[root@Nagios~]# chkconfig ntpd on

[root@Nagios~]# /usr/sbin/useradd -m nagios

[root@Nagios~]# passwd nagios

[root@Nagios~]# /usr/sbin/groupadd nagcmd

[root@Nagios~]# /usr/sbin/usermod -a -G nagcmd nagios

[root@Nagios~]# /usr/sbin/usermod -a -G nagcmd apache

[root@Nagios~]# id nagios

uid=500(nagios) gid=500(nagios) groups=500(nagios),501(nagcmd)

[root@Nagios~]# id apache

uid=48(apache) gid=48(apache) groups=48(apache),501(nagcmd)

二.nagios的安装

[root@Nagios ~]# cd /usr/local/src

[root@Nagios src]# wget http://nagios-plugins.org/download/nagios-plugins-2.1.1.tar.gz[root@Nagios src]# wget https://assets.nagios.com/downloads/nagioscore/releases/nagios-4.1.1.tar.gz[root@Nagios src]# tar zxvf nagios-4.1.1.tar.gz

[root@Nagios src]# cd nagios-4.1.1[root@Nagios nagios-4.1.1]# ./configure --PRefix=/usr/local/nagios --with-comand-group=nagcmd

[root@Nagios nagios-4.1.1]# make all

[root@Nagios nagios-4.1.1]# make install

[root@Nagios nagios-4.1.1]# make install-init

[root@Nagios nagios-4.1.1]# make install-config

[root@Nagios nagios-4.1.1]# make install-commandmode

[root@Nagios nagios-4.1.1]# make install-webconf

[root@Nagios nagios-4.1.1]# cp -rf contrib/eventhandlers /usr/local/nagios/libexec/[root@Nagios nagios-4.1.1]# chown -R nagios:nagios /usr/local/nagios/libexec/eventhandlers

三.nagios plugins的安装

[root@Nagios src]# tar xzf nagios-plugins-2.1.1.tar.gz

[root@Nagios src]# cd nagios-plugins-2.1.1[root@Nagios nagios-plugins-2.1.1]# ./configure --prefix=/usr/local/nagios --with-nagios-user=nagios --with-nagios-group=nagios

[root@Nagios nagios-plugins-2.1.1]# make && make install

四.nrpe插件安装

[root@Nagios src]# wget http://nchc.dl.sourceforge.net/project/nagios/nrpe-2.x/nrpe-2.15/nrpe-2.15.tar.gz[root@Nagios src]# tar zxf nrpe-2.15.tar.gz

[root@Nagios src]# cd nrpe-2.15[root@Nagios nrpe-2.15]# ./configure --prefix=/usr/local/nagios

[root@Nagios nrpe-2.15]# make all

[root@Nagios nrpe-2.15]# make install-plugin

[root@Nagios nrpe-2.15]# make install-daemon

[root@Nagios nrpe-2.15]# make install-daemon-config

# 测试启动

#/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d

# 自带了启动脚本

[root@Nagios nrpe-2.15]# cp -rf init-script.in/etc/init.d/nrpe

[root@Nagios nrpe-2.15]# chmod a+x /etc/init.d/nrpe

[root@Nagios~]# /etc/init.d/nrpe start

注:其实nagios获取信息都是靠/usr/local/nagios/libexec/check_nrpe 这个脚本主动获取nrpe服务端信息

五.配置并启动服务

[root@Nagios ~]# vi /usr/local/nagios/etc/objects/contacts.cfg

define contact{

contact_name nagiosadmin

use generic-contactalias Nagios Admin

email ca0gu0@126.com}

[root@Nagios~]# vi /usr/local/nagios/etc/objects/commands.cfg

define command{

command_name check_nrpe

command_line $USER1$/check_nrpe -H"$HOSTADDRESS$"-c"$ARG1$"}

[root@Nagios~]# htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin

# 检查配置文件是否正确

[root@Nagios~]# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

[root@Nagios~]# chkconfig nagios on

[root@Nagios~]# service nagios start

[root@Nagios~]# chkconfig nrpe on

[root@Nagios~]# /etc/init.d/nrpe start

[root@Nagios~]# chkconfig httpd on

[root@Nagios~]# service httpd start

[root@Nagios~]# touch /var/www/html/index.html

六.配置邮件发送

[root@Nagios ~]# yum -y install mailx

[root@Nagios~]# echo"mail test"| mail -s test ca0gu0@126.com

#如果不配置mail.rc默认会用本地postfix发送邮件

#email send tools

#nano/etc/mail.rc

#setfrom=s0lence@126.com smtp=smtp.126.com

#setsmtp-auth-user=xx@oo smtp-auth-passWord=xxoo

#setsmtp-auth=login

结束!!!!!
